What to write about

Found an error? If a calculation looks wrong, a schematic is mislabelled, or a book chapter won't open, tell us which page and what you expected.
Submitting a circuit — send the schematic, bill of materials and any firmware or PCB files. Contributions are credited to you by name.
Requesting a topology or a book — tell us which converter or subject you need.
Bug reports — for the website, mentioning your browser helps; for the Android apps, the device and Android version.
Partnerships and licensing — for use of our material in teaching or training.

We're a small team, so replies usually take a couple of working days. Messages in English or Urdu are both fine.
